The lava pool here has a secret door (marked with a different texture) leading to two shotgun guys, a cacodemon, a stimpack, a chainsaw, a soul sphere, a rocket, two boxes of rockets, and a light amplification visor. On multiplayer there is also another cacodemon and a baron of Hell. (sector 99)
 * 2) There is a room with two traps with monsters, one of which contains a soul sphere. There is a secret door to the north-east here (marked with a different texture), which opens on shooting, revealing a path to a BFG9000, an energy cell pack, three rockets, four shotgun guys (12 in multiplayer), and 10 lost souls. (sector 107)
 * 3) Towards the end of the level is a series of four crushers. Between the final two is a secret door to the north which opens on shooting, revealing three imps, five rockets, a rocket launcher, three boxes of bullets, a box of shotgun shells, and an armor. (sector 55)
 * 4) The blue key room counts as a secret and is impossible to miss. (sector 150)
